.i LAMP.

Specicaton of Letters Patent No. 28,'717, dated June 12, 1860.

'l'o all 'whom it may concern.'

Be it known that we, JOHN C. JENNISON and AUGUSTUS HALE, of Foxcroft, inthe count-y of Piscataquis and State of Maine, have invented certain newand useful Improvements in Lamps for Burning` Hydrocarbon Liquids; andwe do hereby declare that the same is fully described and represented inthe following specification and the accompanying drawings, of which*Figure l, denotes a top view of a lamp cap having our invention. Fig. 2,is a longitudinal and axial section of it. Fig. 3, an elevation orexternal view taken so as to show the wick tube edgewise. Fig. t, is a.side View of the cap as it appears without the chimney carrier, the samebeing made to show the angular recess of the bayonet connect-ion. Fig.5, is a horizontal section of the lower part of the chimney carrier andthrough its concavo convex projections belonging' to the bayonetconnection.

The nature of our invention consists in the arrangement and applicationof a spring clasp, and angular catch notches on a lamp chimney carrieror holder so as to operate therewith and coniine the chimney theretosubstantially as hereafter set forth. Also, in an improved chimneycarrier as made separate from the cone or deflect-or and the supporterthereof and open for the reception of the deflector and cleaning thechimney and so as to be applied to such deector supporter essentially ashereinafter explained.

In the drawings, A exhibits a lamp cap carrying a wick tube B, and acranked shaft C, the crank of the shaft being connected by a rod D, withthe wick tube in manner so as to enable the said tube to be eitherelevated or depressed in the cap A. The body of the cap is formedconical and foraminous and terminates in a cylindrical rim or flanch asshown at a, which is provided with two right angular notches or recessesb, b, making part of what is usually termed a bayolVithin the rim, a,and resting on the conical part of the cap, is a solai' cone ordeflector, D, and separate from such cone a thin and wide annulus E,tits on and surrounds the rim as shown in the drawings and connects withit by a bayonet connection of which the notches, l), b, make a part andtwo concavo convex projections 0, c, extending inward from the innersurface of the ring E, compose the other part.

Each of such projections we form by striking them up from the ringitself by a punch suitably formed. This saves the necessity of makingthe projections from a separate piece or pieces of metal and attachingthem to the ring by solder, screws or rivets.

Hthin the ring, E, there is a horizontal ring shelf d, arranged as shownin the drawings. On this shelf, the bottom of the glass chimney of thelamp rests. The shelf is constructed with a circular opening, f, toreceive the conical deflector, D, and so extend around it that there maybe a space or air passage, g, circumscribing the deflector and boundedby the circumference of the opening, f. At a short distance above theshelf, (Z, and to the inner side of that part of the ring, E, which isover the shelf, the middle of a circular spring catch or wire, F, ishinged as shown at, m, and in Such manner as to enable the wire to beturned up and down, either toward or away from the shelf. The saidspring catch near each of its two ends is bent at an obtuse or nearly aright angle so as to be capable of being sprung into two angularnotches,h, 7L, formed in the upper part of the ring, E, as shown in thedrawings. Vhen the glass lamp chimney is formed with a shoulder,

lip or ilanch circumscribing. and projecting outwardly from its lowerpart or foot, the spring catch, F, can be caused to clasp the chimneyjust above such lip or flanch and so as to confine the chimney in placeon the shelf, particularly, when the spring catch is within its angularnotches. By pressing together the two ends of the spring catch, andmoving them upward, it may be lifted out of t-he ring, E, far enough toallow of the removal of the chimney from its shelf. The ring, E, and itsshelf we term the chimney carrier, and by constructing such separatefrom the cone or delector, and as a cylindrical ring provided with ashelf and made to close down and fit upon the upper part of the cap, inmanner as described and represented, we are not only enabled to removethe chimney carrier from the lamp cap and the conical deflector, butreadily get at the interior of the lower part of the chimney, whennecessary to cleanse the same,

` and also to fasten the chimney carrier to the lamp cap, by a bayonetconnection. Furthermore, the particular arrangement and application ofthe spring clasp and its angular notches With respect to the chimneycarrier offers an advantage in either readily connecting the chimneyWith the carrier or det-aching the two.

We are aware that in common solar lamps, the chimney carrier, has beenmade with a Wide and fiat Wheel or ring to rest simply on the top of thelamp, and not so as to fit thereto by a bayonet connection or byfriction caused by the ring circumscribing and binding closely uponanother rim or ring, therefore We do not claim such, but

We claim- 1. The arrangement and application of the spring clasp and itsangular notches, to the chimney carrier so as to enable the clasp JOHNC. JENNISON. AUGUSTUS HALE.
